Welcome to cbs this morning. There have been conflicting reports the suspected bomb maker in the belgian terror attacks has been arrested but no confirmation. The man is focused on is Najim Laachroui who was caught on Surveillance Video at Brussels Airport. The blast killed at least 30 people and wounded 260 people and seven americans were hurt in the attacks. Moments ago, belgium observed a moment of silence to honor the victims in the airport and subway station bombings. We have a team of correspondents covering all of the angles of this attack. We begin with Charlie Dagata at Brussels Airport. Reporter good morning to you. Police are widening their search this morning. They are now focusing on a neighborhood about 45 minutes from the airport. And there is news of arrests that were made there. For the victims of the attack here, any news of arrests comes one day too late. Wrun one of the most heart breaking things about yesterdays savage attack on the Brussels Airport and the bomb packed with nails that ripped through the subway car at rush hour. The growing sense that could have and should have been stopped. Police released this picture of the suspects casually pushing luggage thought to be explosives. The man in the middle is ib vertebra him el bakraoui and he and his brother khalid were known as petty gangsters. Khalid in sthe suspect in the train bombing. The man in the hat is the most wanted man in the country before he even stepped into that terminal, belgian mead identified him as Najim Laachroui. They believe he fled the airport in the chaos and may have left his bomb behind. A team carried out an explosion. They raided an address reportedly given to them by a taxi droiveriver who unwittingly drove the three men to the they found another bomb at that location and more bomb making commitment and an isis flag. The imagines of the badly wounded sprawled outside the airport terminal has put the belgian rescue effort under fire too. This passenger camilla told us she was lucky she was in a different part of the terminal when the explosions rang out. We just missed it literally. It was chaos. People crying and screaming and people running around. Reporter belgians have to deal with the horror what has already happened but the real fear it might happen again. Now even as Belgian Police try to close the net on laachroui they are facing questions how he remain undetected for so long and apparently was able to reach this airport and launch those attacks. Thank you, charlie. Isis claimed responsibility for we turn ho Holly Williams in place de la bourkz in belgian. Reporter as belgium remember their dead new information this morning suggesting that deadly bombings in brussels are closely linked to the attacks in november that killed 130 people. More grief and more horror. In another european country, apparently targeted by homegrown terrorists, this time, europe had been bracing for an attack for weeks. Not a big surprise. It was expected, but its very bold. Reporter last night there was a show of European Solidarity as the colors of belgium flag lit up romes fountain and berlins and the eiffel tower. The scenes are reminiscent of paris four months ago and now bombings in brussels could be connected to the paris attacks. Several of the terrorists in paris lived in bulgeintelg. The suspect arrested this morning is suspected to be Najim Laachroui, behind the paris attacks. On friday, belgium people captured abdeslam and days before that, they raided an apartment in brussels and found ammunition and isis flag and abdeslams fingerprints. That apartment, according to the belgium media, was rented by none other than bakraoui, one of the suspected suicide bombers in bristles. They say it may have operated as an isis cell. What we can say for sure is this small country of belgium, population just 11 Million People, has a very big problem with violent extremism. Holly williams in belgium, thank you. At least seven americans are among the wounded in the brussels attack. A group of mormon missionaries were hurt in the airport blast. A former College Basketball player who lives in michigan was also wounded and a couple with ties to kentucky are also missing. Vladimir duj ierthiers is outside a hospital in belgium. Reporter a member of the Armed Services is wounded and several u. S. Residents remain hospitalized this morning recovering that their injuries and includes a former basketball player whose photo has been seen around the world. Of the images of carnage in brussels perhaps none is more striking than this. 37yearold sebastian. I knew when that picture had you wonder. You see all of this blood and you say he is going to make it. Reporter after calling several hospitals in hospital, bellins father was able to speak with his injured son. I think he was speaking very weakly and very slowly because he was in shock. He saw people dead and people dying p. M. Im sure that will stay with him for the rest of his life. Reporter Sebastian Bellin played for two ncaa teams in the u. S. And was a star center for a pro Basketball Team in belgium and was headed home to michigan where he lives with his wife and children. I want to tell him how proud he should be about his determination, about his courage. Reporter in all, Officials Say at least 250 people were injured in tuesdays terrorist attacks including three more mom mormon missionaries in utah. Has burns to his hands and face and shrapnel injuries also. We hope he gets all the way better. Reporter mason wells family says he has been treated for burns and shrapnel injuries. Incredibly, this is not the first time wells has seen terrorism firsthand. He was standing near the finish line three years ago when terrorists detonated explosives at the boston marathon. Wells was also in france but not in paris when the attacks occurred in november. The state Department Said it does not know of any americans killed in the brussels attack, but several americans are reportedly still unaccounted for, including this brother and sister from new york. Family members say they were on the phone with them, heard an explosion, and got cut off. The siblings havent been heard from since. A couple from kentucky is also reported missing. Worrisome, indeed. Thank you, vladimir. Cbs news has learned the fbi is sending a team to help with in the u. S. Experts are analyzing those imagines captured by the Airport Security cameras. A government says its rare to have such clear pictures of terror suspects. Law enforcement has stepped up security at major transportation hubs around the country. Jeff pegues is at one of those hubs and joins us from our nations capital. Reporter good morning. You will see this beefed up security presence at transportation hubs and cities like new york, los angeles, and key points around this city, washington, d. C. , like this metro station behind me. The department of Homeland Security is working with local and state Law Enforcement authorities to coordinate this enhanced police presence. Meanwhile, we have learned that u. S. Investigators are looking for symbolism and imagines of those suicide bombers, perhaps in an effort to prevent the next attack. The two on the left are wearing black. The clock of the isis flag. They are not hiding their faces. And they were wearing black gloves on their hands. Were likely used to hide some sort of detonator. As for the man dressed in the white jacket who Police Identify as Najim Laachroui, the bomb maker, officials believe he is the controller or facilitator of the operation. Notice his face was covered unlike the other two men and he was wearing a hat. Investigators believe that may not be a coincide and, all along, the plan was for him to escape. Here in the u. S. , the fbi says that it is stepping up surveillance of potential terrorism suspects even as they say and other u. S. Official say there is no specific of credible threat against the United States. Charlie . Thank you, jeff. Former cia Deputy DirectorMichael Morrell is a cbs news Senior Security contributor. Good morning. Good morning. What do we know and what is the significance of the man who is the subject of this manhunt . Right. So he is significant for two bomb maker. Right . If he has been captured, lets will be able to tell authorities, if he is willing to talk, a lot of information. He was probably trained in iraq and syria and he was probably trained with a large number of other bomb makers who may be at large in western europe so he may know who they are. So he may be able to provide authorities an awful lot of intelligence. Here is what concerns me. Terrorists have struck a European Capital two times in the past four months. They are on a roll. You said, yesterday, they are winning. Right. What is next . This network in europe is very large. We are talking about 5,000 guys who went from western europe to iraq and syria to fight, right . Some of them are still there. Some them have died on the battlefield and some are coming and hardens jihadists and more radicalized and now the threat we now face. Western intelligence, u. S. , european intelligence simply dont know how many individuals are out there, how many cells are out there. They are worried. Because we are separated here in the United States by an ocean, does that make us any safer . So its so in the last nine to 12 months, 15 months, isis has built this attack capability in western europe. Its much more difficult for them to do that here for all sorts of reasons. The muslim communities here are nowhere near as isolated as they are there. Its much easier to get people there. They had more people to go and fight. Its harder to do it here but not impossible. If we dont degrade isis in iraq and syria and around the world we will face an attack like this someday here, absolutely. Belgian authorities are getting a lot of criticism today for how they handled this. This guy was hiding in plain sight. Is the criticism fair . Of it is not. What is fair criticism is the Belgian Police dont do a good job of Community Policing in the largely muslim areas. They dont know the community right well and they dont get the intelligence they need but its also unfair because their governments have not given them the resources they need to do all of the surveillance they require and the job is huge. Michael morrell, thank you. New York City Police commissioner bill bratton and the new York City Police administrator will be here. Ted cruz slipped further behind republican frontrunner donald trump. Jeb bush is throwing his support behind cruz to stop Donald Trumps march to the republican president ial nomination.

Dean reynolds is there with how the president ial hopefuls plan to confront the terror threat. Reporter the brussels tragedy was seized upon by golden opportunity to flex some of their muscle of their own in the political process. President obama is happily at yucking it up with the castros, communist dictators. In the political fight of their life, ted cruz and john kasich thought it was talking tough. If i were president i would have cut short my visit and flown home. Reporter noticely absent from the events was donald trump but made up for it by writing mr. Obama sounds so ridiculous making a speech in cuba. Cruz decried the Political Correctness driving decisions about Homeland Security and writing in a statement to prevent a tam attack in the u. S. , muslim neighborhoods should be controlled and secured by Law Enforcement. Where there is an expanding presence of radical islamic terrorism, we need Law Enforcement resources directed there and National Security resources directed there. Trump agreed, without getting into detail. I would support that, 100 . How do you do that and find out where muslim neighborhoods are . That was too much for kasich. No. I dont think we should be patrolling muslim neighborhoods. I dont know how you would do it. Democrat Bernie Sanders saying this from Jimmy Kimmels couch. At the end of the day, we cannot allow the trumps of the world to use these incidents to attack all of the muslim people in the world. That is unfair. Reporter taking a shot across the aisle, Hillary Clinton called out her republican opponents saying their ideas wont keep america safe. What donald trump, ted cruz, and others are suggesting is not only wrong, its dangerous. Now House Speaker paul ryan will be speaking today on the state of american politics and it will be interesting to hear what, if anything, he has to say about suckerpunching demonstrators, baiting opponents or hurling insults at competitors.
